problem understanding placeOrder sequence flow

[martin_alley]

Hi,

I'm new to magento and php

I'm looking at writing a hosted payment page integration in magento2.

I'm going through the QuoteManagement placeOrder function .

function placeOrder($cartId, PaymentInterface $paymentMethod = null)

I'm consfused that it calls $paymentMethod->setChecks, but that PaymentInterface doesn't define such a method?

How does that work?

Thanks

Martin

`QuoteManagement` class implements `\Magento\Quote\Api\CartManagementInterface` which has placeOrder() .

PaymentInterface defined payment related methods and data which can be used in placeOrder().

If it helps please give "Kudos" and  "Accept solution".

The issue is that PaymentInterface doesn't seem to have a method "setChecks()" defined on it.
